Delayed closure of what valve occurs during splitting of S2 sounds?
What causes a wide splitting of S2?
anything that delays RV emptying
What causes a paradoxical splitting? What is the order of valve closing?
anything that delays LV emptying
pulmonic closes before aortic in this situation
Inspiration would increase the intensity of sounds from what side of the heart?
What does the hand grip manuever accomplish?
increases vascular resistance
Does the hand grip manuever increase or decrease the intensity of left-sided heart pathologies?
Would the hand grip manuever make a MVP occur earlier or later?
What does standing do to venous return?
What does the valsalva manuever do to venous return?
What does standing/valsalva manuever do to most murmurs?
weaken their intensity
What murmur can standing/valsalva manuever increase the intensity of?
What does rapid squatting do to preload?
What does rapid squatting do to venous return?
What murmur can rapid squatting increase the intensity of?
Would rapid squatting increase or decrease the intensity of an MVP?
What are the three presentations of aortic stenosis upon exertion?
Woud mitral/tricuspid regurgitation be a systolic or diastolic murmur?
Where does an aortic stenosis murmur radiate?
Where is a VSD murmur the loudest?
at the tricuspid valve
Would an MVP occur during diastole or systole? Early or late?
Name three conditions that may cause an MVP?
papillary muscle rupture
Would an aortic regurgitation murmur be heard in diastole or systole? Early or late?
What are two presentations of aortic regurgitation that could be seen on physical exam?
What murmur produces an opening snap?
What is the most common cause of mitral stenosis?
chronic rheumatic fever
What is the most common cause of a PDA?
Where is a PDA best heard?
left infraclavicular area
What voltage is the action potential for a cardiac myocyte?
What voltage is the action potential for a cardiac nodal cell?
